摘要： The fuel injection system has a high-pressure pump, by which fuel is pumped into a reservoir, with which injectors disposed on cylinders of the engine communicate. A feed pump pumps fuel out of a fuel tank to the high-pressure pump and a fuel metering device triggered by a control unit and disposed between the feed pump and the high-pressure pump controls the fuel quantity delivered to the high-pressure pump. The fuel metering device is formed by a clocking valve, which is opened and closed in pulse-width-modulated fashion by the control unit, and the fuel quantity delivered to the intake side of the high-pressure pump is proportional to the opening duration of the clocking valve.

摘要： Fuel injection system having a feed pump by which fuel is pumped out of a fuel tank to the intake side of a high-pressure pump pumps fuel into a reservoir as a function of engine operating parameters. A fuel metering device is provided for adjusting the fuel quantity pumped into the reservoir by the high-pressure pump. An electrically actuated blocking valve is disposed between the feed pump and the high-pressure pump, and by means of this valve the high-pressure pump can be disconnected completely from the feed pump. By means of the blocking valve, it can still be attained that no fuel is pumped by the high-pressure pump even if the fuel metering device does not provide complete sealing.

摘要： The fuel injection system has a high-pressure pump which pumps fuel into a reservoir to be supplied to injectors disposed at the engine cylinders. A feed pump supplies fuel to the high-pressure pump. The high-pressure pump has at least one pump element including a pump piston that defines a work chamber and is driven in a reciprocating motion; the work chamber has a communication with the compression side of the feed pump, in which an intake valve opening toward the work chamber is disposed, and through which valve fuel flows into the work chamber upon the intake stroke of the pump piston. The intake valve has a valve member, which is urged in a closing direction by a closing spring, and the closing spring is braced at least indirectly on the pump piston; with an increasing intake stroke of the pump piston, the closing force exerted on the valve member by the closing spring becomes less. A minimal opening differential pressure of the intake valve is less than 0.9 bar.

摘要： The fuel injection device for an internal combustion engine comprises a feed pump which has an electric drive, by which feed pump fuel is fed from a fuel storage tank into a low-pressure region to the suction side of at least one high-pressure pump. The high-pressure pump pumps fuel into a high-pressure region in which at least one injector is provided to inject the fuel into the internal combustion engine. The fuel injection is controlled by an electric control device. Arranged in the low-pressure region is a pressure sensor which is connected to the control device. The electric drive of the feed pump is activated by the control device in order to set a feed quantity of the feed pump which is variable as a function of at least one operating parameter of the internal combustion engine and/or of the high-pressure pump. The drive of the feed pump is in particular activated by the control device in such a way that, at a high load of the internal combustion engine and/or at a high rotational speed and/or at a high fuel temperature, a greater fuel quantity is fed by the feed pump into the low-pressure region than at a low load and/or a low rotational speed and/or a low fuel temperature.

摘要： The invention relates to a high pressure injection system having a fuel tank, a connection line between the fuel tank and a high pressure pump for sealing the fuel, wherein the high pressure pump is connected to at least one fuel injection valve via a corresponding connection line. According to the invention, at least a partial volume of the fuel sealed in the high pressure pump is fed back to the fuel tank from said fuel injection valve by leakage in the fuel injection valve via a return line connected to the fuel tank. An essential characteristic of the invention is that the high pressure injection system comprises a cooling line that connects the fuel tank or the low pressure region to the high pressure or a return of the high pressure pump via a mixing point with the return line. It is thereby possible to cool the fuel in the return lines between the fuel injection valve and the fuel tank.
